It depends on the county of course, but in my experience service workers at many “touristy” countries seem to benefit directly from tourism.

For example, some of the workers at resorts in Thailand went to college and studied Tourism, a major I didn’t even know existed, and their wages come directly from the tourist industry.

What countries in particular are you thinking of where the locals are very unhappy to see more tourists? I’ve heard Japan might be in that category, and the United States certainly feels that way, but did you experience this yourself?
